NiftiMapsMasker Class for masking of Niimg-like objects. NiftiMapsMasker is useful when data from overlapping volumes should be extracted (contrarily to :class:`nilearn.maskers.NiftiLabelsMasker`). Use case: Summarize brain signals from large-scale networks obtained by prior PCA or :term:`ICA`. Note that, Inf or NaN present in the given input images are automatically put to zero rather than considered as missing data.
This reports shows the spatial maps provided to the mask.
The masker has 63 spatial maps in total.
